Zzzzz...
Faced with Kaido's punch, which was imbued with advanced Haki, Yami still chose not to dodge.
He converted his stamina into a green light, covered his fist with it, and clashed with Kaido's punch.
The next moment, both Yami and Kaido showed a hint of pain on their faces.
On the surface, it seemed more severe for Yami, as the Dark-Dark Fruit made him suffer double the pain.
But in reality, Kaido was the one who was more uncomfortable.
From his flesh and bones, down to the cellular level, he was being attacked by gamma rays.
"What is this ability?"
As Kaido continued to trade blows with Yami, he secretly increased the output and defense of his Haki and subconsciously asked, "Why can you penetrate my Haki and defense without imbuing your attacks with Haki?"
"Oh, it's gamma rays. They can penetrate most substances in the world and cause damage to them," Yami said casually, not hiding anything, while also increasing his stamina consumption to convert it into more gamma rays.
"What kind of stuff is that?"
Kaido didn't understand at all. He continued to punch at Yami's infuriatingly calm face and complained, "Aren't you a Logia-type Dark-Dark Fruit user? Is this also a power of darkness?"
"No, it's the ability of the Paramecia-type Op-Op Fruit."
The corner of Yami's mouth curved up slightly, revealing a set of neat white teeth. He smiled and said, "I'm just an unremarkable multiple Devil Fruit user."
"..."
Kaido was slightly stunned, his movements pausing for a moment.
Bang!
Seizing this opportunity, Yami punched Kaido in the face. The terrifying force and the highly penetrative gamma rays sent Kaido flying, causing him to spit blood from the corner of his mouth and his face to sting with pain.
But Kaido quickly stood up. His reaction was different from Doflamingo's, Robin's, and the others'. He shouted excitedly, "A multiple Devil Fruit user! Such a thing actually exists in this world? No wonder this guy can grow giant-sized. I thought it was because of his race, but it turns out it's another Devil Fruit ability!"
"..."
As Kaido's words spread across the roof of the Skull Dome, Ulti, Black Maria, and the others who were watching from a distance all had looks of utter astonishment on their faces.
The only one who could maintain his composure was King the Conflagration, whose face was hidden behind a black helmet.
If he were to take off his helmet, his reaction would probably be similar to the others'.
"A mul... multiple Devil Fruit user?"
"Hey, hey... am I hearing things? Did Boss Kaido just say that 'Black Hole' Yami is a multiple Devil Fruit user?"
"One person can eat multiple Devil Fruits... isn't that something that only exists in fantasy, something I'd only dream of?"
"Hiss... if that's true, then these seas are about to be thrown into chaos!"
"..."
After Ulti and the others came to their senses, these Devil Fruit users all spoke with looks of horror and trembling voices.
Their gazes towards Yami were as if they were looking at a monster.
A monster that defied their understanding, a monster that made them subconsciously feel fear and rejection.
"Worororo... King, bring me my Hassaikai!"
The person who was different from the others was, as always, Kaido.
He let out his unique laugh and shouted to King the Conflagration, who was watching from the sky. Then, he looked at the approaching Yami and grinned ferociously, "Since you're a multiple Devil Fruit user, then I won't hold back!"
"That's just what I was thinking!"
Yami repeated those words and grinned. "Then... the warm-up is over!"
The moment his words fell, a black shadow filled Kaido's vision.
Yami, who had been a dozen meters away, appeared before him out of thin air. His giant-sized fist, no longer covered in the green light that could penetrate everything, was now coated in a black substance. He smashed it directly into Kaido's face.
But unlike the previous punches, after this punch landed, Yami let out a soft shout, "More-More: Ten Times Heavy Punch!"
Boom---
In an instant, Kaido's massive body vanished into thin air, just like Yami's teleportation.
If it weren't for the massive shockwave that erupted where he had disappeared, distorting the air and tearing apart the ground, one would have thought he had also teleported away...
With the exception of those with extremely strong dynamic vision, almost no one saw Kaido disappear.
Only those powerhouses who had been watching with their Observation Haki active had their mouths agape, once again wearing looks of utter astonishment.
In their perception, the invincible Boss Kaido had turned into a huge afterimage, flying out of the Skull Dome, and even out of Onigashima, at a speed more exaggerated than a sniper bullet.
To send Boss Kaido flying out of Onigashima with a single punch... what kind of power is that?
If I were to take that punch, wouldn't I be instantly blown to bits?
"Roar..."
A deafening roar spread across Onigashima from far to near.
Kaido, who had been sent flying out of the island, had transformed into a several-hundred-meter-long azure dragon and was rapidly flying back towards the roof of the Skull Dome.
"Blast Breath!"
Upon his return, Kaido did not immediately revert from his beast form. He opened his mouth and gathered a huge ball of fire, about to spew a massive pillar of fire downwards.
Seeing this, the members of the Beasts Pirates who were watching on the roof all had their expressions change in shock.
"Kaido-sama, don't use that move! You'll destroy the Skull Dome!"
"Governor-General, I'm here! That move will kill me!"
"Run! Get out of here, quickly..."
Just as these spectators were panicking and preparing to flee the roof of the Skull Dome...
The scene that followed immediately silenced them, leaving them with their mouths agape, staring at the sky in stunned silence.
Before Kaido could finish charging his attack, a hundred-meter-tall giant suddenly rose from the roof of the Skull Dome. He threw an uppercut at Kaido's jaw, sending the Blast Breath that had been aimed downwards shooting up into the sky.
A massive pillar of fire connected the sky and the roof of the Skull Dome.
If it were nighttime, it would surely be an incredibly dazzling firework, visible from both Onigashima and Wano Country.
If someone were on the coast of Wano Country, facing Onigashima, they would also be able to vaguely see two giant shadows.
A hundred-meter giant versus a hundred-meter dragon, as if a mythological story had manifested in the real world.
